CLUTCH MECHANISM FOR THE DRIVING-SHAFTS OF LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 394,194, dated December 11, 1888.

Application filed August 30, 1888. Serial No. 284,165. (No model.)

To all whom it may concern;

Be it known that I, AUcUsT MATTHEs, a subject of the King of Saxony, residingin the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Clutch Mechanism for the Driving Shafts or Axles of Locomotive-Engines, which in'lprovement is fully set forth in the following specification and accompanying drawings.

My invention relates to improvements in clutch mechanism for the driving shaft or axle of a locomotive-engine; and it consists in a mechanism to cause the driving-shaft to revolve without revolving the driving-wheels, or to impart motion to the driving-wheels, whereby the locomotive may be readily and quickly stopped.

It further consists in the combination and adaptation of parts in the attainmentof the desired ends.

Figure 1 represents a vertical sectional view of a clutch mechanism embodying my invention. Fig. 2 represents a sectional View on line 03 00, Fig. 1. Fig. 3 represents a sectional view on line y 3 Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates the driving-shaft of a locomotive-engine.

B designates the driving-wheels, each of which is formed with -a sleeve, 0, encircling a portion of the driving-shaft, to which latter is rigidly secured the hub D of a disk, E, and to said disk is attached a disk, F, thus forming a casing, F.

The hub D is encircled by an arm, G, in which is journaled a roller, H, and to said arm G is connected one end of a spring, J, the other end thereof being connected to the easing F, as is clearly shown in Fig. 3 of the drawings. From this construction it is evident that the casing is secured rigidly to the driving-shaft, and consequently turns therewith, and also that the sleeves of the drivingwheels rotate independent of said shaft.

K designates collars, having the hubs L thereof encircling the sleeves, and secured firmly thereto by means of keys, said disks being connected by cross-bars M, or in any other suitable manner. One of the hubs of the collars is formed with an annular groove or channel, N, in which is received a pin or stud, P, on the shifting-levm' Q, for moving the collars on the sleeves of the driving-wheels.

The operation is as follows: hen the mechanism is in the position shown in Fig. 1, the driving shaft and case will revolve without revolving the driving-wheels. To cause the drivin wheels and shaft to revolve, the collars are shifted by means of the lever Q to bring the cross-bars M in the path of movement of the arm carryin the roller. Said roller then contacts with the cross-piece, as shown in Fig. 3, and imparts motion to the collars and sleeves of the driving-wheels, causing said wheels to revolve. To cause the shaft only to revolve, the shifting-levers are operated to move the cross-bar of the collars out of contact with the arm, as shown in Fig. 1.

The spring J prevents injury to the arm when struck by the cross-piece. It will also be noticed that the casing is constructed so that the arm projects therefrom and abuts against the rim of said case when it is out of use, as clearly shown in Fig.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination, with the driving-shaft having an arm, of the driving-wheels loosely mounted on said shaft, and means carried by said wheels for engaging the arm and causin the shaft and wheels to revolve, substantially in themanner and for the purpose described.

2. The combination of the driving-shaft, the arm carried thereby, the driving-wheels having sleeves encircling said shaft, the collaror disk carried by the sleeve, and means for shifting said collar to cause the engagement thereof with the arm on the driving-shaft, substantially as described.

3. The combination of the driving-shaft, the chamber or case carried thereby, the arm, the spring arranged in said case and connected with the arm, the driving-wheels having the sleeves encircling the driving-shaft, the disks carried by the sleeves and connected by crossbars, and means for shifting said disks to throw the cross-bars thereof in the path of movement of the arm, substantially in the manner and for the purpose described.

4. A device for causing the driving-shaftof a locomotive-engine to revolve Without revolving the wheels, consisting of sleeves adapted to freely encircle said shaft, a chamber connected With said shaft, an arm in said chamber, a collar fixed to said sleeves, and a on said shaft, a casing having a hub secured to said shaft, collars With hubs secured to the sleeves by splines, and one of said hubs having an annular groove, cross-bars connecting said collars, an arm secured to said casing and having its outer end adapted to either engage said cross-bars or pass under the same, and a shifting-lever With stud resting in said annular groove of collar-hub, substantially as described.

AUGUST MATTHES.
